-Due to the principle of constant proportions
-It can be accurately measured with a simple chemical analysis
The amount of salt in the water. Near the surface of the open oceans salinity is in general between 3.3% and 3.7%
How does chlorine enter the oceans?
In open ocean evaporation affects the salinity of the oceans, in closed oceans the lack of sunrays cause greater salinity levels.
Water
Water
No. Primarily because of the amount of fresh water draining into it, the Black Sea has a very low salinity and the Mediteranean has a higher than average salinity.
Salinity varies in different parts of the world's oceans based on the amount fresh water which runs into the ocean. This comes in the form of rainfall, ice, and river discharge.
Oceans are big water bodies. Salinity is due to the presence of minerals in water.
salinity
There are several factors that affect salinity. Some of the main factors include evaporation and precipitation which will affect the salinity of oceans and seas.
3.1-3.6% salinity
The world's oceans have a salinity of about 3.5%
